Hello. This is JH from My Korean Guide.
If you are planning to visit Gangnam, COEX Mall is probably at the top of your list. It houses the famous Starfield Library, hundreds of shops, and even an aquarium.
However, there is one big problem: It is a giant maze. Even locals get lost here. I have seen many tourists wandering around looking at confusing maps.
Today, I will share a perfect 1-day itinerary for COEX Mall & Gangnam, designed by a local so you don’t waste your time getting lost.
Before we start, remember this Tip. You don’t need to look at your phone map constantly. Just look at your feet.
COEX has colored navigation lines (Byeolmadang-gil) on the floor to guide you to major spots.
If you feel lost, find these lines on the ground and follow them. They are the fastest way out of the maze.

Do not aimlessly walk around the mall. Follow the blue line and head straight to the landmark first.

If you are traveling with kids or want a romantic date spot, the COEX Aquarium is a must-visit. It is one of the largest aquariums in Korea, housing over 40,000 sea creatures.

COEX is not just a mall; it is the “World Trade Center” of Seoul. Various international conferences, K-Pop events, and exhibitions are held here every week.
Before you visit, check the schedule. You might stumble upon a travel fair, a coffee expo, or a K-Pop fan event!

To maximize your efficiency, follow this route:
Don’t forget: If you are lost, look at the floor!
Gangnam is a dynamic mix of the ultra-modern and the traditional. With the floor navigation lines, you won’t have to worry about getting lost. Just follow the colors and enjoy the vibe of Seoul.
